What do you mean by jack this thread ?1. MM - 5 years for a phone is a really long time. I would temper my expectations there if I were you.
2. Is it the talking on the phone while driving or holding the phone to your head while driving? The former, if using a hands free device or in car connection is no different than engaging in a conversation with a passenger. In fact, since that conversational partner is not present, you don't have to feel compelled to look at him at all.
BTW, we have completely jacked this thread.
Anyway i brilliantly discussed hand held vs hands free in another post. But since you missed it i'll go it over again.
For simplicity lets call it HF - Hands Free and HH Hand Held )
The difference is actually very minor.
Those who hold it to the ear have a harder physical time driving most noticeable when making left turns.
The number one problem of cell usage while driving is the distraction from the road to the phone call.
This occurs both HF and HH.
Physically looking at who you are talking to obviously takes your eyes off the road. That's a given.
But its its the distraction of the mind that i'm talking about.
That occurs whether you see the person or not.
Also phone call conversation tends to be more intense then a person in the car conversation.
You're more adapt to force your point over a phone where you're not 100% sure if the reviver is getting your message.
If someone sitting next to you then you know if they are really listening to you or not.
So my point is
1) HF vs HH only makes a slight difference and its physical.
2 ) in person conversation is not as distracting as a cell phone conversation. They are different. You may not view it differently but i do and i think others do too. That is why laws about driving with cell phones are being written. And more will be written later.
